Latest development on crashed Germanwings Plane 4U 9525

– 1:07 p.m. ET: One of the black boxes of the downed Germanwings plane has been found, French Interior Minister Bernard Cazeneuve said Tuesday.

– 12:54 p.m. ET: The Germanwings plane is obliterated, with no piece of debris larger than a “small car,” said Gilbert Sauvan, the president of Alpes de Haute Provence region.

Sauvan, a high-level official who is being briefed on the operation, said that human remains are strewn for several hundred meters. Helicopters have flown over the crash site but have not been able to land.

Authorities may not be able to retrieve any bodies Tuesday, according to Sauvan, with the frozen ground complicating the effort. Wednesday may not be much easier, with snow in the forecast.

Florian Adamik, a municipal official in Haltern, earlier told CNN that 16 students and two teachers from one German high school — called Joseph Koenig Gymnasium — were booked on the flight.

A crisis center has been established at the city hall in Haltern, which is about 48 miles (77 kilometers) north of Duesseldorf’s airport.

Full story:

A Germanwings Airbus A320 plane crashed Tuesday in the foothills of the Alps in southeastern France with at least 150 people on board, according to Germanwings managing director Oliver Wagner.

French Prime Minister Manuel Valls told reporters he fears all those aboard the flight from Barcelona, Spain, to Dusseldorf, Germany. The plane crashed near Digne-les-Bains, in the Alpes de Haute Provence region, Valls said.

“The conditions of the accident are not yet clear but lead us to believe there will be no survivors,” Hollande said.

Spain’s King Felipe VI, who cut short a state visit to France as news of the crash broke, said there was a “high number of Spaniards, Germans and Turks” on the doomed Germanwings flight.

Spanish Prime Minister Mariano Rajoy tweeted that he will return to Madrid, put together a “crisis team” and send a minister to France.

Relatives of those believed to be on the flight, fearing the worst, have started to gather at Barcelona airport, where a crisis center has been set up.

German Chancellor Angela Merkel said Tuesday that “we don’t know much about the flight and the crash yet. And we don’t know the cause.”

Merkel said that she’s been in touch with France’s President and Spain’s Prime Minister, with all agreeing to “help each other in any form.”

There were “many” Germans on the plane, she told a news conference, adding that the suffering of the families concerned was “incredible.” “We have to think of the victims and their families and their friends,” she said.

Merkel said she was sending two ministers to France on Tuesday and would travel to the crash site on Wednesday to see it for herself.

German Foreign Minister Frank-Walter Steinmeier said the German government had set up a crisis center in response to the “terrible news” and was in close contact with the French authorities.

“In these difficult hours, our thoughts are with those who have to fear that their close ones are among the passengers and crew,” he said.
